- Industrial Energy Conservation
- Heat Recovery
- Heat exchangers - transfer heat from hot effluents to incoming cold gases/liquids
- Large surface areas - long, narrow pipes
- Pipes made from good thermal conductor e.g. copper
- Slow flow rate for more effective exchange
- Heat exchangers - transfer heat from hot effluents to incoming cold gases/liquids
- Insulation
- Covering things (espcially storage tanks) with material with low thermal conductivity
- High Volume Storage
- Small surface to volume ratio for small heat loss
- Spherical containers have SA:V
- Combined Heat and Power Station
- National Grid
- Low current electricity to reduce heat loss by resistance
- High voltage maintains power
- Power = Current x Voltage
- Transformer used to increase voltage/reduce current before use
- Integrated Manufacture
- All stages of manufacture occur on same site (less transportation)
- Recycling
- Less energy used than making products from scratch
- Often higher transport energy use
- Heat Recovery
